Big brewers have suffered “injury by a thousand cuts” as “consumers have been bitten by the flavor bug,” said Duane Stanford, the editor of trade publication Beverage Digest.

A decade ago, the top 10 brands made up nearly 66% of the beer industry. Their share has shrunk to 50% as craft beers have gained, according to the trade publication.

But there are signs that craft beers are starting to slow down, too.

Pabst expanded too quickly and had to cut jobs last year. So did Summit Brewing and Green Flash. Magic Hat and Pyramid parent North American Beverage shipment volume is down 14% over the past five years. Smuttynose, New Hampshire’s largest independent brewer, is being auctioned off.

Shipments fell at Boston Beer Co. and Sierra Nevada, the two largest craft breweries. Six of the top seven craft brands’ shipments fell in 2017, according to Beer Marketer’s Insights.

The craft industry is maturing and may not have much more room to expand. Craft drinkers may also be starting to settle into their favorite brands.

“You can only take so much choice. There is a limit at some point,” Stanford said.
